Need help in downloading Sun specification

Hi all,
I am preparing for SCBCD. As directed by many exam takers here, I want to read the sun EJB specification. But I am facing some issues in downloading it. The Sun download page here gives the specification for EJB 3.1 and JPA 2.0 . But SCBCD tests EJB 3.0 , so which version should I download? Same is the case for JPA specification too.
